Thailand: 5 baht 2013, y446, eventual counterfeit or something else? Date wrong! [解決]

I just got this in a swap, much to heavy since much too thick!

Can somebody measure their 2013, please, to help to find out, what I have?

Thanks in advance

Ole

If you have compared the on top depicted coins then they are obviously not the same type.

N#1640 

N#7236 

Thanks, I see it now, but I did a search in numista like this:

now, what did I do wrong?

Apart from that, I just believed in the date my swap partner had given 2013 = 2556 พ.ศ.๒๕๕๖, but in reality it is 2006 -2549  พ.ศ.๒๕๔๙, I just verified, so of course it all went wrong, also the search because of the wrong date.

Sorry for disturbing you all. It taught me from now on to check the dates on received coins myself, and don't believe in my partners…..
